Write a C program to create a new array containing the middle elements from the two given arrays of integers, each of length 5.

C Code:

#include <stdio.h>
#include <stdlib.h>

// Function prototype for 'print_array'
void print_array(int parray[], int size);

int main(void){ 
    // Declaration and initialization of variables
    int arr_size;
    int a1[] = {10, 20, -30, -40, 30 };
    int a2[] = {10, 20, 30, 40, 30};
    int arr_size1 = sizeof(a1)/sizeof(a1[0]);
    int arr_size2 = sizeof(a2)/sizeof(a2[0]);

    // Printing elements in the original arrays
    printf("Elements in original array are:\n");  
    print_array(a1, arr_size1);
    print_array(a2, arr_size2);  

    // Creating a new array with specific elements from the original arrays
    int result[] = { a1[2], a2[2]  };

    // Calculating the size of the new array
    arr_size = sizeof(result)/sizeof(result[0]);

    // Printing elements in the new array
    printf("Elements in new array are: ");  
    print_array(result, arr_size);
}     

// Definition of the 'print_array' function
void print_array(int parray[], int size)
{
    int i;      
    for( i=0; i<size-1; i++)  
    {  
        // Printing each element with a comma and a space
        printf("%d, ", parray[i]);  
    } 
    // Printing the last element without a comma and space
    printf("%d ", parray[i]);  
    // Printing a new line to separate the elements
    printf("\n");   
}

Sample Output:

Elements in original array are:
10, 20, -30, -40, 30 
10, 20, 30, 40, 30 
Elements in new array are: -30, 30
